Since I have recently graduated from the depends under garments and pads during the day to undies and pads, I have done some self research on which undies work best with pads(at least for me).
I have tried various brands with little success in keeping the pads in just the right place and help preventing scrotal leakage,until yesterday. A brand sold at JC Penny's works well. They are the Stafford performance. These undies do not have the ordinary escape route that normal briefs have. But who of us is using that any way? It does however have a little pouch in the front that with the pad makes a nice little home for the "twig and berries" to nestle in. Thus preventing any thing but full pad leaking
With these it makes me more comfortable to go out in public with out the OOPPS of side pad leakage. Enjoy!
